Custom fields

The campaign custom fields are exposed in campaign.customfields.

{{ campaign.customfields['field-key'] }}

A missing key returns an empty string: the template does not error.

Presence and iteration:

{% if 'field-key' in campaign.customfields %}
  {{ campaign.customfields['field-key'] }}
{% endif %}

{% for key, value in campaign.customfields %}
  <li>{{ key }}: {{ value }}</li>
{% endfor %}

Methods: campaign.customfields.get('key'), .keys(), .values(), .items().

Values by field type

Type	Value
Text	string
Flag	"true" / "false"
Menu	selected option (string)
Date	ISO date YYYY-MM-DD (string)

Dates are ISO strings: use format_date for DD/MM/YYYY output:

{{ campaign.customfields['event-date'] | format_date }}   {# 28/07/2026 #}

note

All non-archived campaign custom fields are available in the theme and may appear on the public site. Do not put in a campaign field any data that must not be public.
